- Abstract
- Lattice regularization of gravity theory provides new opportunities for studying Big Bang physics. It is proved that in the 4D lattice gravity model studied here, there exists a high-temperature phase characterized by the vanishing of the mean energy-momentum tensor of matter and the collapse of space into a point. The existence of a low-temperature phase in the long-wavelength limit is also shown, whose geometric properties and dynamics correspond to known concepts: the Universe's expansion initially follows an exponential law and then smoothly transitions to a power-law regime.
